That question came up a couple weeks ago in Sunday school and so I started thinking about it. Why is it so important? The creation of the Earth was not the beginning. We were Spirits living with Heavenly Father before the Earth was created. The creation of the Earth was the beginning of how Heavenly Father's plan started. He gave us a beautiful world so we could come and gain bodies and live a life. It is very important for us to know where we came from and how we got here. Everyone questions that sometime in his or her life. So Heavenly Father has given us the knowledge of where we came from and how we got here and it all started with Adam and Eve.
